Abstract

The crystallographic features of the ferroelectric domain structures in (Sr_1-xBa_x)Bi₂Ta₂O₉ single crystals have been examined by transmission electron microscopy. The unique 90° domain structures were found in these single crystals. In SrBi ₂Ta₂O₉ with x = 0, particularly the majority domains with the ±[110]_t polarization vectors in the tetragonal notation arc divided by the minority ones with the ±[11̄0]_t vectors, which were observed as a curved-line contrast in dark field images.
